¿Qué es el Cálculo de Dosis de Insulina?
El cálculo de dosis de insulina es un método utilizado por personas con diabetes para determinar la cantidad de insulina necesaria antes de las comidas. Combina dos componentes: la dosis de carbohidratos (basada en la cantidad de carbohidratos que se consumirán) y la dosis de corrección (para ajustar la glucemia actual al valor objetivo). Este método es fundamental para el control glucémico adecuado y la prevención de complicaciones de la diabetes.
Preguntas Frecuentes
How is basal insulin dose calculated?
Basal insulin is typically 40-50% of the total daily insulin (TDI) requirement. TDI is estimated at 0.5-0.8 units/kg/day for type 1 diabetes and 0.3-0.5 units/kg/day for type 2 diabetes. This calculator provides an initial estimate that should be individualized.
What is the correction factor (insulin sensitivity)?
The correction factor, or insulin sensitivity factor (ISF), indicates how much 1 unit of rapid-acting insulin will lower blood glucose. It is calculated as 1700/TDI (rapid analogs) or 1500/TDI (Regular insulin). This helps correct high blood glucose levels.
How do I calculate mealtime insulin (bolus)?
Mealtime insulin is calculated based on carbohydrate ratio (grams of carbohydrate covered by 1 unit of insulin) plus correction dose if blood glucose is above target. The calculator provides these values based on the TDI method.
Can I use this for children with diabetes?
Yes, but pediatric patients often require higher insulin doses per kg (especially during growth spurts and puberty). Typical TDI in children is 0.7-1.0 units/kg/day. Always consult with a pediatric endocrinologist for pediatric dosing.
